Detailed Description

Grab override is a new feature in the X Input Extension that allows clients to intercept key or button events even if there is an existing device grab. This allows for global shortcuts such as Alt+Tab to work at all times.

Benefit to Fedora

Device grabs result in a number of UI deficiencies. For example:

if a device grab is active, Alt+Tab will not work

if a device grab is active, the volume keys do not work

if a device grab is active, the screen saver cannot kick in

Allowing for grab overrides resolves these issues.

Scope

Defined and release new upstream X Input Extension protocol version, integrate support into the X server and libX11.

How To Test

TBD

User Experience

This is a plumbing layer feature only and will not directly be visible until applications or toolkits make use of the feature.

Dependencies

This feature requires upstream releases for xorg-x11-server and xorg-x11-proto-devel. Since we ship the packages anyway, we'll just take whichever one is out at the time.

Contingency Plan

None necessary.

If the feature isn't ready upstream in time, it will not be part of our xorg rpms.
